InstructIon and operatIng manual
set-up procedure
• Engage the manual override and move the
valve to the mid-travel position�
• Move the local selector to OFF and then
simultaneously press OPEN and STOP� Select
the language and then enter the password
according to the instructions (see “Entering
the set-up mode”)� When the message
displayed is “SET-UP MODE OK?” press
yES� Press yES to select the actuator set-up
menu, and then press yES again to start with
the stroke limits routine�
• Press YES if the closing torque limit is correct
or NO to scroll the list of available values�
When the value is correct, press yES�
• Press YES if the opening torque limit is
correct or NO to scroll the list of available
values� When the value is correct press yES�
• Press YES if the rotation to close is correct
(CW or CCW), or NO to change�
When the value is correct press yES�
• Press YES to set the close limit, or NO and
then yES to set the open limit�
close limit type
Press yES if the close limit type is correct
(torque or position), press NO to change it�
Press yES when the type is correct�
close limit by position
• Move the local selector to LOCAL. The local
controls can be used�
• Move the valve to closed position (by CLOSE
control or by handwheel)�
• Move the local selector to OFF.
• Press YES to confirm.
• Press YES to continue with the open limit
setting, or press NO and again NO to repeat
the close limit setting procedure� Press NO
and then yES to exit from the stroke limits
routine�
close limit by torque
• Move the local selector to LOCAL. The local
controls can be used�
• Press the CLOSE control. The actuator moves
in closing direction and when the configured
torque value is reached the motor is stopped
and the new position limit is memorized�
• Move the local selector to OFF.
• Press YES to confirm.
• Press YES to continue with the close limit
setting, or press NO and again NO to repeat
the close limit setting procedure� Press NO
and then yES to exit from the stroke limits
routine�
open limit type
• Press YES if the open limit type is correct
(torque or position), press NO to change it�
Press yES to confirm�
open limit by position
• Move the local selector to LOCAL. The local
controls become active�
• Move the valve to open position (by OPEN
control or by handwheel)�
• Move the local selector to OFF.
• Press YES to confirm.
• Press YES to exit, or press NO and then YES
to repeat the close limit setting procedure�
9� SET-uP ROuTINES
9.1 actuator set-up
9.1.1 set stroke limits
This routine allows the actuator to be
configured according to the type of valve it is
mounted on�
The following parameters will be set:
- Opening and closing torque limits: from 40%
to 100% of the nominal torque. The nominal
torque corresponding to 100% is set in-house
and is stated in the name plate menu for
reference�
- Close direction: clockwise (CW) or
counter-clockwise (CCW)� Most valves require
clockwise rotation of the stem when viewed
from the handwheel� Engage the manual
override and check if the valve closes with
clockwise or counter-clockwise rotation of
the handwheel�
- Close and open limits type: by position or by
torque� use the table below to choose�
Valve type

Gate (solid, flexible and split wedge), globe, metal seated
butterfly valves

open limit by torque
• Move the local selector to LOCAL. The local
controls become active�
• Press the OPEN control. The actuator moves
in opening direction and when the configured
torque value is reached the motor is stopped
and the new position limit is memorized�
• Move the local selector to OFF.
• Press YES to confirm.
• Press YES to exit or press NO and then YES to
repeat the close limit setting procedure�
If parameter “direction to close” is changed,
both limits (open and close) must be set�
set-up procedure
• Move the local selector to OFF and then
simultaneously press OPEN and STOP� Select
the language and then enter the password
according to the instructions (see “Entering
the set-up mode”)� When the message
displayed is “SET-UP MODE OK?” press
yES� Press yES to select the actuator set-up
menu, press NO and then press yES to select
the torque set-up routine�
• Press YES if the opening torque limit is
correct, press NO to scroll the list of available
values� Press yES when the value is correct�
• Press YES if the closing torque limit is
correct, press NO to scroll the list of available
values� Press yES when the value is correct�
Before leaving the stroke limits routine the
microprocessor calculates the new value of
the position resolution� If the stroke turns
are less than 2�7, the message “error re-try”
appears and the stroke limits procedure must
be repeated�
9.1.2 torque set-up
The output torque limits to close or to open
may be configured between 40% and 100%
of the nominal torque stated on the actuator
nameplate�
